The current investigation evaluates metal (loid)s biomonitoring using algae as well as the metal(loid) pollution of seawaters and sediments in the northern part along the Persian Gulf. Algae, seawater, and sediment samples were collected from four coastal areas with different land applications. The concentration of Ni, V, As, and Cd in abiotic samples (seawater and sediment) and four species of algae (Enteromorpha intestinalis, Rhizoclonium riparium, Cystoseira myrica, and Sargassum boveanum) was measured using an ICP-AES device. Concentrations of potentially toxic elements in seawater, sediments, and algae species followed the trend of "Ni˃V˃As˃Cd." The area of Asaloyeh (with the highest industrial activity) and the Dayyer area (with the lowest industrial activity) provided the highest and lowest amounts of metal(loid)s pollution, respectively. The average concentrations of V and As in four algae species significantly differed for all sampled areas. Obtaining the bio-concentration factor (BCF) > 1 for seawater and < 1 for sediment indicated that the studied algae have the ability to efficiently concentrate metal(loid)s from seawater and the limited accumulation of metals in sediments. According to the Nemerow pollution index, the order of metal(loid)s pollution for the studied areas estimated as Asaloyeh>Ganaveh>Bushehr>Dayyer. Algae species of C. myrica and E. intestinalis can often serve as suitable biological tools for monitoring seawater and sediment quality.
本研究评估了藻类在波斯湾北部沿海地区的金属（类）生物监测以及海水和沉积物中的金属（类）污染情况。从四个具有不同土地利用情况的沿海地区采集了藻类、海水和沉积物样本。使用电感耦合等离子体发射光谱仪（ICP-AES）测定了非生物样本（海水和沉积物）和四种藻类（肠浒苔、裂叶冠须藻、美舌藻和泡叶马尾藻）中的 Ni、V、As 和 Cd 浓度。海水、沉积物和藻类中潜在有毒元素的浓度遵循“Ni>V>As>Cd”的趋势。Asaloyeh 地区（工业活动最活跃）和 Dayyer 地区（工业活动最少）的金属（类）污染程度最高和最低。四个藻类物种中 V 和 As 的平均浓度在所有采样区域均有显著差异。海水的生物浓缩因子（BCF）>1 而沉积物的<1 表明研究中的藻类具有从海水中有效浓缩金属（类）的能力，以及金属在沉积物中有限的积累。根据内梅罗污染指数，研究区域的金属（类）污染顺序估计为 Asaloyeh>Ganaveh>Bushehr>Dayyer。美舌藻和肠浒苔等藻类物种通常可以作为监测海水和沉积物质量的合适生物工具。
